8 Claims.

The object of this invention is to arrange the members of a refrigeration system in order to make same compact, noiseless, and easilyA appliedto refrigeration enclosures.

Insofar as I am aware in the prior arts, the compressor and the motor and air fan member of a refrigeration system are not surrounded by the condenser member, the condenser member of system is not cooled by drawing air into a space surrounded by a condenser, the moving mech- :mism members are not supported by the condenser member, the noise vibrations produced by the moving mechanism are not absorbed by the condenser. The condenser is not supported on one side of a plate and communicating with the freeze members ofthe system on the other side of' the said plate, a hole is not included in the side 0f a. refrigeration enclosure adapted to receivle the freeze member, and to be covered by the plate which supports the members of a refrigeration system; the apparatus comprising the refrigeration mechanism, the condenser member, the freezing members` the supporting plate as a complete refrigeration unit are not supported bythe top or any other side of a refrigerator enclosure so that the freeze member extends through a hole in the said side and the plate secured to the said side.

Whereas: The present invention of refrigerating process and apparatus, the compressor, the fan and the motor members of the apparatus are surrounded by the condenser member of the apparatus. The condenser is cooled by drawing air into the space surrounded by the condenser and is.l discharged from the said space. The moving mechanism is supported on the condenser memher, the vibration produced by the moving mechanism is absorbed or neutralized by the condenser member. The condenser coil is supported on one side of a plate and communicates with freeze members on the other side of plate. A hole is included in any of the sides of a refrigerating inclosure which is adapted to receive the freeze member and to be covered by the said plate l which supports the refrigeration mechanism and freeze members, and the entire assembled appa.- ratus is supported by any of the sides of a refrigeration enclosure so that the freeze member extends into the enclosure through a hole in the said side and the plate is secured to the said side.

A more specific description and explanation of invention may be had by referring to the accompanying drawing.

l is amotor adapted to drive the compressor 2. Motor I is secured to the bracket 3 by any suitable means but preferablyl by screws lA, IB, IC- and I'D. Compressor 2 is secured to bracket 3 by any. suitable means but preferably by. screws 2A and. 2B. Part o! the invention contemplates in a broad sense securing the mechanism of a refrigeration system to the. condenser 4, so that the4 condenser 4i will support the said mechanism and so that the mechanism be surrounded by the condenser so that the assembled apparatus will be compact. Also. part of the. invention contemplates. in a broad sense supporting the mechanism on a. condenser coil so that any noiseA vibrations` produced by the working mechanism can. be absorbed by the condensercoil, due to the flexibilityy or lack of rigidity common to coils.

iis a pipe which.` communicates with the condenser 4 and the compressor 2. Vapor or gas is compressed hv the compressor and is. delivered to the compressa t through pipe 5.

The vapory or ses compressed by compressor 2, is hot, due to the of compressing same. This vapor after it is conveyed to the condenser through i is condensed and cooled and is delivered to pipe which is either an extension of condenser @ik l. er a pipe extending from the coil 4 to. the expansion Valve 1, and which communicates with the condenser coil and the expansion Valve, and adapted to convey refrigerant fiuid to the expansion valve Il.

The expansion valve l communicates with the freeze member 8 and adapted to maintain the condensing pressure in condenser- 4 and to deliver condensed refrigerating fluid to the freeze member. y

The freeze member 8; is adapted to vaporize the refrigeratirrgV received from the expansion valve 1,. andthe freeze member communicates, with a compressor suction line 9 and the said suction line 3 communicates with the compressor 2. The freeze member 8 may be of any suitable design, but the coil design is preferred as due to the iiexibilitles common to coils any shifting of the position of pipe 9 or the members it is attached t0, Willbe adjusted bythe flexibility of the said coil or any noise producing variation produced by the moving mechanism and which may telegraph through pipe 9v will be absorbed or neutralizedby the said freeze coil 8,.

The bracket 3 which supports the compressor and the motor is secured to the condenser coil in any suitable manner and tor any suitable place in the condenser coil but preferably to the outer end of thevsaid coil so that a maximum portion of the coil is utilized to absorb vibration produced by the moving mechanism it'supnorts; @JSG the air into the space surrounded by condenser 4 and discharging of same from the said space by an air fan I I is preferred, and is part of the present invention. It may be noted that the condenser coil restson theA plate I2 and that any air drawn into the space surrounded bythe said coil must be drawn through part of the spiral spacing of the said coil, also that'the motor I occupies part of the space surrounded bythe :condenser coil 4, but that there is an annular space between the coil and the motor. into the space surrounded by coil 4 is discharged from the said space through 'the' said annular space and also through part of the spiralspacing of the coil 4 as is self evident.

The condenser 4 is secured to. a plate I2 by any suitable means for securing the said condenser to the said plate. However, the welding of the brackets 4A and.4B to they condenser and securing these brackets to the plate I2 by screws I2A and I2B is preferred.

The motor and the compressor as is commonly known are heat producing members. of a refrigerating system and the condenser as iscommonly known Ais the heat dissipating member of a refrigerating system and said condenser as is commonly known communicates with the expansion valve and cold producing member of the system and said cold producing member communicates with the compressor. y In the present invention the heat producing and heat dissipative members of a refrigeration system are secured to one side of plate I2 and the cold producing members are on the other side of the plate I2 but communication with the condenser andthe compressor, said communications 6 and 9 extending through -the said plate I2. f

I4 is the top or any side 'offa refrigeration enclosure, I3 is a hole in the top'or any sideof said enclosure adapted to receive the cold producing members 'I and 8,. so that the said members extend into the said refrigeration enclosure.

The said hole I3 iscovered by plate I2, and plate I2 is secured to the side -I4 by any suitable means but preferably by screwsA I2A, and I 2B which may extend through plate I2 ,into or through side I4.

The freeze member is held in' place by pipes 6 and 9 and bracket I5. Bracket I5 serves to 'support the member I5 andto lessen or to balance any strain which may be exerted on pipes 9 and 6.

Also part of the invention contemplates in a broad sense assembling the motor, the compressor, the condenser on one side of a plate and the freeze members on the other side of the plate, inserting the freeze member inr a hole in a refrigerating enclosure and `covering the said hole with the said plate. i
